I have to make a small reversing gear assembly and i've proposed it to use 2 spur gears and a crown face gear. Now I have to do the models but i'm not finding much information of the modeling of a crown gear and how to make the teeth? Am I making it too complicated? I have it in solidworks now but it doesn't look right.

Edit: Actually I know how to make teeth. but how do I determine the shape? I just took the tooth form from the spur gears and cut them across the crown shape. Small Bio
